BlackBerry shares jumped 5.6 percent on recall of a prior earnings beat, then gave back the gain as the broader market drifted without direction.
What happened
BlackBerry stock moved 5.6 percent, a move bigger than 90 percent of its daily moves over three years. The move was tied to a story recalling that the company beat last quarter's earnings per share estimate by 33 percent, with the next report due September 24. The move touched roughly 100 billion dollars of market value.
Why it matters
A past earnings beat resurfacing as a driver suggests traders are positioning ahead of the next report. The size of the move, against a calm, split market with no clear direction, shows how little news it takes to swing a small, out-of-favor name when volumes are thin.
The case against
The move is a reaction to a stale data point from last quarter. The company has given no new guidance. If the September report merely meets expectations, the trade has no footing and this spike reverses as fast as it came.
What settles it
Whether BlackBerry issues new guidance or pre-announces any metric before the September 24 report.
